This invention relates to a cellar drain valve and embodies a structurewhich is an improvement over what is shown in Patent No. 2,235,308 whichissued March 18, 1941.

It is an object of the invention to provide a valve of this kind havingnovel and improved means for maintaining a closure member or plug ineffective position, together with means whereby such member or plug canbe readily released and moved into inoperative position when desired. v

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved cellardrain valve whereby certain important advantag'es are attained, as willbe hereinafter more fully set forth.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein:

B denotes the upper bell end portion of a drain pipe which is embeddedin the floor of a cellar or elsewhere as may be preferred, with its topend substantially flush with the floor surface.

Engaged within the bell B of the pipe and resting upon the usualinternal shoulder I is a substantially cylindrical body member 2 fullyopen at its bottom or inserted end and which is herein disclosed asbeing gradually reduced in diameter from its bottom to its top on apredetermined degree to provide a suitable surrounding space 3 for theplacement of packing of any desired kind.

The body member 2 is of such dimensions as to extend a slight distanceabove the bell end portion of the drain pipe and said upper or top endis provided with an inwardly disposed surrounding flange 4 defining arelatively large central opening 5, the top portion of the wall of whichis rabbeted, as at 6, to provide a support for a perforated filter plate1.

This plate 1, as herein disclosed, is substantially concavo-convex inform and when applied has its convex face downwardly disposed. Theperiphery of the plate I is defined by a surroundingflange or rim 8 atthe concave side of the plate and said rim or flange 8 at its uppermargin carries a surrounding outstanding lip 9 which engages within therabbet 6 hereinbefore referred to.

The top or outer face of the flange 4 is flat and is directly engaged byan annular gasket ll! underlying the peripheral portion of the valve orplug member M. This gasket l0 snugly surrounds a depending annularflange l l at the central portion of the member M and which, when themember M is in closed position, substantially snugly engages within therim or flange 8 of the filter plate-1. I

The central portion of the member M has rigid therewith an outstandingelongated post 12 which is freely disposed through an opening I4 in thebasewall 15 of an inverted cup-like boxing l6 herein disclosed asintegrally formed with substantially the central portion of a lever L.

The lever L at one extremity is provided with a laterally disposed anddepending lug H which is of a bifurcated type and straddles the outerend portion of an outstanding lug l8 rigid with the upper portion of theside wall of the body 2. Disposed through the lugs I1 and I8 is a pintle[9 whereby the lever L is supported for movement to swing across the topor outer end of the body member 2 or to be swung away therefrom.

When the lever L is in its lowered position and which is a positionradially across the top or outer end of the body member 2, the valvemember M is in closed position and is tightly maintained in suchposition by the expansible member 20 interposed between the member M andthe base wall l5 of the boxing l6. As herein disclosed, this expansiblemember 20 constitutes a coil spring of requisite tension surrounding thepost [2.

The lever L is of a length to extend entirely across and slightly beyondthe top or outer end of the body member 2 and the outer or free endportion of the lever L is formed to provide the transversely spaced andoutwardly disposed plate arms 2| which are substantially in parallelwith the longitudinal axis of the lever L. These plate arms 2| alsoextend a distance below or inwardly of the lever L and between the lowerportions of these plate arms 2| is pivotally held by the pin 22 alaterally disposed mounting lug 23 rigid with the central portion of alatch arm 24. This latch arm 24 is of a length to extend below the upperor top end of the body member 2 when the member M is in closed positionso that the inwardly disposed holding lip 25 of the latch arm 24 mayhave proper engagement from below by the properly positioned outstandingkeeper 26 rigid with the upper part of the body member 2.

Interposed between the upper or outer end portion of the arm 24 and theend wall of the lever L between the plate arms 2| is an expans iblemember 21 also herein disclosed as a coil spring of requisite tensionand which operates to constantly urge the lower or holding end of thearm 24 inwardly so that the lip 25 will be in effective relation withrespect to the keeper 26. To facilitate the proper engagement of the lip25 with the keeper 26 as the lever L is swung to bring the member M intoclosed position, the top surface of the keeper 26 at its outer portionis outwardly and downwardly beveled, as at 28.

The central portion of the arm 24 has rigid therewith an outstanding arm29 to the outer or free extremity of which is suitably anchored, as at30, an end portion of a pull line 31 which may be a cord or wire orotherwise as may be properto comply with the requirements of practice.This pull line 3| is of desired length so that it can be readilyoperated to swing the lever L away from the body member 2 to open thevalve so that it will not be necessary for the person to wade into thewater to reach the valve under flood conditions.

The lug 23 is provided with an outstanding finger 32 positioned forcontact from below with the lever L at a point between the plate arms 2|to provide means for positively limiting the extent of inward swingingmovement of the end portion of the arm 24 carrying the lip 25.

From the foregoing description it is thought to be obvious that a cellardrain valve constructed in accordance with my invention is particularlywell adapted for use by reason of the convenience and facility withwhich it may be assembled and operated.

I claim: A valve of the character described, comprising a taperedcircular body open at its upper and lower ends, means at said open upperend forming a valve seat, a concave-convex strainer disposed within saidupper open end and having an encircling supporting lip, the said upperopen end of the body having an annular recess to receive said strainerlip, said lip having its upper side disposed flush with the surface ofthe said upper open end, a fiat valve member above the said upper openend of the body at the outer side of said annular recess, an annularflange on the underside of said valve member disposed in the upper sideof said strainer, a gasket encircled about said flange and seated on thesaid upper open end of the body and the flush surface of the saidstrainer lip, a lever disposed across the open end of the body tooverlie the valve member, pivot means between one end of the lever andthe body, cooperating means between the other end of the lever and thebody for releasably coupling the lever with the body, a pin carried bythe valve member and extending through the lever, and a springinterposed between the valve member and the lever and encircling saidpin.
